HOW TO USE THIS MANUAL

Read and save these instructions. This manual is designed to assist qualified field service, operating and maintenance personnel with the installation, operation, and maintenance of Greenheck canopy type kitchen hoods and accessories.

Procedures described in this manual should be followed in the order they appear, with attention to all safety and caution statements.

RECEIVING, HANDLING & STORAGE:

Upon receiving the equipment, check for both obvious and hidden damage. If damage is found, record all necessary information on the bill of lading and file a claim with the final carrier. Check also to be sure that all parts of the shipment, including accessories, are accounted for.

If a kitchen hood must be stored prior to installation, (or for any long period) it must be protected from dirt and moisture. Indoor storage is recommended. For outdoor storage, cover the hood with a tarp to keep it clean, dry, and protected from UV (Ultra Violet) radiation damage.

NOTE: The kitchen hood is shipped with a plastic film attached to the surface. The film is to protect the panels from minor scratches during handling and shipment. This film must be removed prior to assembling the system. When the system is operating, the film will melt and bake on to the surface. Once the film is removed caution should be used in handling the parts.

Improper storage which results in damage to the unit will void the warranty.

NOTE: The functions listed above require the control center to be wired to the exhaust fan and plumbed.

WATERWASH SYSTEM FUNCTIONS:

Greenheck waterwash hoods are designed for three primary functions:

1) Capture and contain the effluent produced by the cooking process.

2) Remove grease and other contaminants from the airstream with a series of extraction baffles.

3) Wash the baffles and other surfaces within the exhaust plenum to remove contaminants.

Normal Exhaust Operation and Contaminant Collection:

The system's exhaust fan is manually controlled by a push-button switch (Start Fan) located on the face of the waterwash control station. The exhaust system operates until the Stop Fan/Start Wash push-button switch is pressed.

Optional Continuous Cold Water Mist:

The optional continuous cold water mist is controlled by the same push-button switch (Start Fan). With this option, all hoods with this option are sprayed continuously when the fan is on. This feature acts as a spark arrestor for solid fuel applications, as per NFPA 96, Standard for Ventilation Control and Fire Protection of Commercial Cooking Operations. This does not have to be all hoods - can be just the solid fuel hoods.

Cleaning Cycle:

A factory programmed controller triggers the waterwash function when the exhaust fans are shut down at the end of each day’s cooking operations. A pressurized spray of hot water and detergent cleans the hood in a timed cycle. When the cleaning cycle is complete, the controller runs the exhaust fans briefly to remove steam from the exhaust system. The controller then automatically resets itself. If the kitchen is closed for a day, the wash cycle will skip as long as the start fan button has not been pushed

For multiple hoods totalling over 20 ft. 0 in. in length, systems are designed to wash each hood or group of hoods sequentially. (Hoods totalling up to 20 ft.0 in. in length can be washed as a single unit.)

April 2005

Fire Mode (Optional):

The waterwash system also provides water spray for the exhaust plenum when the system is in fire mode. This is in addition to the hood’s automatic fire suppression system. When the fire suppression system discharges, it activates the waterwash system (without the detergent) and the optional continuous cold water mist to spray water within the exhaust plenum and turns on the fan circuit. The system will shut off when the fire protection system is reset. It can also be shut off manually by turning off the water flow in the waterwash control station. Exhaust fan will be on, Supply fan off

The system shown includes a vacuum breaker for backflow prevention. Some state plumbing codes require a reduced pressure backflow preventer. See page 7 for detailed control panel layouts of each type.

Typical Installation:

April 2005

SYSTEM COMPONENTS:

Hood:

The hood is shipped from the factory prepiped and ready to install. All waterwash components within the hood are complete and ready for connection to hot water, electrical sources, the sanitary sewer drain and optional cold water. All piping to and from the waterwash control station and the hood is by others. Wiring from the control panel to the hood (for lights) is by others. All plumbing and wiring must conform to plumbing and electrical codes. See Figure 1(previous page) for typical installation and location of electrical and plumbing components.

Duct collars are also mounted at the factory unless requested otherwise.

Waterwash Control Station:

The waterwash control station contains all of the water and electrical controls in two separate compartments. (See Figs. 2, 3, 4, 5, 6 & 7). The electrical side includes all electrical components, connections, and on/off switches. These switches are illuminated and are mounted on the face of the cabinet. The water side includes hot water connections, pressure/temperature gauges, the detergent reservoir and pump, water hammer arrestor, the water solenoid valves, and optional continuous cold water mist piping.

Vacuum Breaker (shipped loose for field installation):

The vacuum breaker is installed at the highest point in the system’s piping to prevent backflow when there is no water pressure to the hood. It must be installed a minimum of 6 in. above the hood water supply line (See Figs. 2, 3 & 4).

Reduced Pressure Backflow Preventer - RPBP (shipped loose for field installation):

Where building codes require a reduced pressure backflow preventer, it will be provided in lieu of a vacuum breaker when ordered. The reduced pressure backflow preventer is installed beneath the control panel (See Fig. 5, 6 & 7). May by ordered mounted in 48 in. tall cabinet.

Detergent Pump-Related Components (shipped loose for field installation—installed in RPBP systems. See page 42 ):

• Detergent line check valve

• Detergent tube (1/4 in. I.D., 3/8 in. O.D.)

Optional Features:

24 Hour / 7 Day Timer:

This feature allows the cleaning cycle to begin at any preset time after the fans are shut down, rather than immediately after. This allows time, for instance, for completion of dishwashing to avoid a shortage of hot water. Fans must be turned OFF just as with the standard cleaning cycle. Maximum six start times.

Multiple Hoods Sequenced Wash:

Where more than one hood must be washed, the control station is set up to wash each hood individually in a prescribed sequence. This ensures that there will be adequate hot water for all hoods. Individual water solenoid valves are provided for each hood to be washed in a multiple sequence. Maximum five sequences.

(Sequence solenoid valves are shipped loose for systems with vacuum breakers or optional continuous cold water mist. They are mounted in the control station for standard systems with reduced pressure backflow preventers.)

Low Detergent Indicator Light:

A sensor and indicator light are available to alert the operator when the detergent tank requires filling.

Continuous Cold Water Mist:

This feature continuously sprays a fine water mist in the exhaust plenum of the hood. The continuous cold water mist is controlled by the same push button switch as the fan.

INSTALLATION

NOTE: If you have a Backsupply Plenum (BSP), this must be installed before the hood. Please

see Page 13.

For Wall/Single Island Style Hoods, prior to installation, check with local authorities having jurisdiction on clearances to combustible surfaces, etc.

With the hood still inside its packing crate, position the unit beneath its installation location. Carefully remove the packing

crate. Place some protective material on the floor next to the crate to avoid damaging the hood as it is tipped on its side. (See Fig. 8) Tip the hood carefully onto the protective material. If you have filler panels, install them now. Please see page 16.

If you have integral filler panels, no additional installation is needed.

Insert

⁄2 in. diameter threaded rod (by others) into hanger brackets on hood top. (Fig. 9, Pg. 10) Check the engineering drawings for proper hood height above finished floor. Greenheck recommends that the hoods be hung 6 feet 6 inches above the finished floor. Raise and hang hood from adequate roof or ceiling supports. All hanger brackets must be used and hood must be properly supported while lifting to prevent damage or distortion to the hood. The hood must be hung level

to or slightly pitched toward the grease drain.

1. Find the center of the Backsupply Plenum.

2. If the Backsupply Plenum is less than 9 ft. 10 in. wide, cut opening at

the suggested location, centering the opening over the center of the backsupply Plenum. (see Fig. 10A)

3. If the Backsupply Plenum is greater than 9 ft. 10 in. wide, divide the

width of the backsupply by four. This will give you the center of each half. Cut openings at the suggested location, centering the duct collar over the center measurement of each half. (see Fig. 10B)

4. Place the duct collar(s) over the opening, fastening with screws or tack

welds every four to six inches. (see Fig. 11)

Hanging the Hood

Before hanging the hood according to the hood installation instructions, please check the following:

1. Make sure the Backsupply Plenum is properly secured, as described in steps 5 and 6, page 13.

2. If the ductwork for the Backsupply will not interfere with the hood installation, it should be connected now.

3. Any filler panels should be attached to the hood before the hood installation. See page 16 for instructions.

4. For Canopy Hoods: Lift the hood, and position it so the filler panels are resting lightly on the top outside edges of the Backsupply. The Backsupply is used to position the hood only, it is not intended to hold any hood weight. (See Fig. 13)

5. Connect the remaining ductwork for the Backsupply and the hood. It is recommended that caulk be applied at the mating seams and surfaces of the Backsupply, the hood, and the wall.

Air Diffusers

The air diffusers, located at the bottom of the backsupply (See Fig. 14), will need to be cleaned as often as the application dictates. Inspect periodically to determine the cleaning schedule.

1. To clean the air diffusers, unfasten the screws. Remove the air diffusers from the Backsupply Unit, and wash in the sink or dishwasher.

2. Insert the air diffusers at an angle from the bottom, and rotate so the forms are downward. Rest the diffuser on the internal angles. (See Fig. 15)

3. Refasten with the stainless steel screws.
